PAUL 1F. man, ioF foHroAqo', -ILL'nvoIsA A ,further obge of` t hef! isili-he pr'a6n-f `4flagged'at tht-gliela hier wh in itheige is; a simp e com inatioliiii arrangifiiftif parts for effectively holding sensitized printing sheets in proper contact with the negative plate or film.

A further object of the invention is the provision for facilitating the positioning of a sensitized printing sheet under a negative plate or film for proper exposure.

Other objects will appear from the detailed description hereinafter' set forth.

The invention consists in the combination and arrangement of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawing. illustrating the preferred form of construction, and in which;

Fig. 1 is a front elevational view 'of the invention.

Fig. 2 is a rear view of the invention.

Fig. 3 is a sectional detailed view of the same, taken substantially on line 3 3 of Fig. 1.

Fig. 4 is a sectional detailed view of the same taken substantially from line le-4 of Fi 3.

is well known to those skilled in the art that, in a device of the character herein mentioned and hereinafter described, if the sensitized printing sheet is not positioned so that its entire adjacent surfaces contact with the negative plate or film` that the finished photograph or print will be uneven in shade and possess unsightly high spots rendering the photograph or print defective.

It is therefore one of the many objects of the invention to provide a simple combination and arrangement of parts for assuring uniform contact `between the surfaces of the printing sheet and the adjacent snrfaces of the negative plate or film.

To accomplish this and other objects. of the invention. I provide a frame 10 defining` a back 11 and side walls 12 having intnrned edge portions 13 defining together with the side walls 12 and the back 11 opposite channels 14. A tongue 15 is struck inwardly from body of the back 11 to provide a stop ting sheet 19 fdirietoffsirchmaterialas n r tillage are the parata;sharewares- 0f negative plate are supported when mount,- ed with their edge portions 21 disposed in the channels h v the tongue 15. This tongue serves in its principal capacity as a guiding member for guiding the pressure plate 13 into uniform contact with the separating sheet which in turn is forced by the pressure plate into uniform Contact with the. sensitized printing sheetfor pressing this sensitized printingr sheet into uniform contact with the negative plate 2O for proper exposure beneath the negative plate. i

The pressure plate is urged into pressing position by the resilient fingers 22 disposed in staggered relation and struck inwardlv from the body of the back 11. i i In assembling the separating sheet. sensitizcd printing sheet and nega-tive plate, it

is apparent that the tongue 15 serves to h facilitate proper positioning of these memhers and also that the tongue 15 serves to guide the pressure plate when urged into contact with the separat-ing sheet.

As illustrated in Fig. 3 of thc drawing the separating sheet 19 is scored transversely as at 2 intermediate its top and lower edge portions permitting the portion 3 of this sheet to bc folded rearwardly together with a portion of the sensitized printing sheet away from the negative plate when the separating` sheet, sensitized printing sheet and negative plate are partially withdrawn from confined position in thc frame with the score line 2 of the separating sheet disposed exterior of the frame. This permits one to observe the sensitized printing sheet without completely withdrawing the printing sheet from confined position in the frame.

From the description herein it is manifest that. l provide a simple combination and arrangement of parts for effectivelyy urging pressing action of the pressure. plate and that such combination and arrangement of parts greatly facilitate the assembly of the separating sheet` sensitized printing sheet and negative plate.

lVhen a negative film is substituted for the negative plate '20 a, sheet 0f glass is substituted for the negative platte and this Vllin is disposed between the Asensitized printing sheet and glass :it :i pointindicated` @t 2 2', Fig. 4.

'hile l have shown und ,deseribedvtlie preferred forin 0f my invention, it is to be understood that various changes. sind alterations may be eai'iqied out in manufacture without departing 'from the spirit Of :the invention or the scope ofthe-appendedelaims;
